DBEDGING' DEVICE.

To all whom it may concern:

Be it known that I, Josnrrr W. BAILEY, a citizen of the United States,and a resident of Langley, in the county of Aiken and State of SouthCarolina, have invented an Improvement in Dredging Devices, of which thefollowing is a specification.

My present invention relates generally to devices including a dredgingor scraper bucket and scooping, hoisting, carrying and dumping means forthe bucket, my ob ect generally being to provide an arrangement in whichthe bucket travels upon a carrier line adapted to be flexibly slackenedand tautened to raise and lower the bucket andin which the bucket may bedumped at any point throughout the entire span of the carrier line whiletraveling at full speed in either direction and can be brought to astand-still and dumped to a pile or into cars also at any desired point.

In carrying out the objects of my invention I provide an arrangementsuch as shown in the accompanying drawings, which form a part of thisspecification, and in which- Figure l is a side elevation of thecomplete mechanism.

Fig. 1 is a plan view of the mast, its supports and the adjacent parts.

Fig. 2 is a side elevation of the bucket carriage.

Fig. 3 is a front elevation thereof.

Fig. 4 is a side elevation of the dumping bucket.

Fig. 5 is a vertical longitudinal section taken therethrough, and

Fig. 6 is a plan view thereof;

Referring now to these figures it will be noted that the mast A isstepped upon a roller mounted frame A supported upon a track B and isprovided at its upper end with side pulleys a over which a traveling 1guy line C is extended, the rear end of this line being provided with asheave c and the forward end thereof carrying the block C havingseparate wheels for the back line and the carrier lines as best shown inFig. 1

A guy line A is also extended rearwardly from the mast A and providedwith a sheave a, and through this sheave and the rear sheave 0 of thetraveling guy line G extends the anchor line A the ends of which areattached to dead men 00 whereby to effectively support the mast as wellas the car- Specification of Letters Patent.

rier and back lines, as also best shown in Fig. 1

The complete operating and controlling means are mounted upon a frame Dsupported upon wheeled trucks D movable upon tracks E. This frame Dcarries the drums F, G- and H of the back line F, carrier lines G andhaul lines H respectively and it is to be understood that these severaldrums are provided with gearing whereby they may be independentlyrotated and with brakes whereby they may be independently controlled toput tension upon their respective lines. The frame D is also providedwith a stationary upright pulley support D carrying a series of pulleysover which the respective lines extend.

There are two carrier lines G, as will be particularly seen by referenceto Fig. 1, formed by passing a single cable around the block G from thedrum G and thence back again with its end anchored at 9 upon the frameD, the upper and lower carrier lines respectively extending betweenpulleys i and i and 2" and i at the opposite sides of the bucketcarriage I, it being noted from Figs. 2 and 3 that this carriageconsists of side plates spaced apart by a plurality of thimbles i andhas a lowerintermediate pulley f downwardly around which the outerportion of the back line F, after passage around the block C, extends.

The bucket K, which is generally rectangular in shape, as seen byreference to Figs. 4 to 6 inclusive, is provided with rings k at itsfour corners, by means of which it is flexibly suspended from thecarriage I, by chains K, and being thus suspended from its four corners,is effectively from accidentally overturning.

The bucket K which has upright side and rear walls K is provided with asingle ring is at its rear to which the outer extremity of the back lineF after passage around the carrier pulley f as before mentioned, isattached. The forward edge of the bucket is provided with rings 70extending forwardly from the forward edges of its side walls K for thereception of chains H to which the outer end of the haul line H issecured, other chains H over said forward end of the haul line beingconnected to the carriage I.

Thus by flexibly slackening and tightening the carrier lines G, thebucket K may prevented I brake upon the back line drum F dumping thematerial therefrom.

be raised and lowered and by operating the drums F or H, the bucket maybe drawn in opposite directions when-in either raised or loweredposition, it being understood that when the haul line H is drawn to movethe bucket in one direction, all tension is removed from the back tinuedmovement of either for the rial therein or after collection.

When it is desired the bucket is desired purpose of collectingmatetransporting such material to dump the bucket the is applied, andthe back line being held thereby, the rear end of the bucket is raisedto the position shown in dotted lines in Fig. 1 for The same operation,though reversed, is'true when the bucket is being drawn by the backline, the haul line being stopped when it is desired to dump the bucket.

From this it will be seen that the bucket may be dumped without the useof a buffer or attachment to the carrier lines and may therefore bedumped at any point through out the entire span between the operatindrums and the mast, either when at a still or when moving fast or slow,and further without the use of any slide or frame work. i

It will be seen furthermore that when the bucket is drawn in loweredposition by the haul lines H in'the digging operation, more or;1esstension upon the back line F will cause the bucket to dig more or lessat the will of the operator.

It will also be seen that the double carrier lines provide strength and,as rigged the entire arrangement provides great power with light engineduty, either the back line F or the haul line H beingentirely slackenedwhen the bucket is drawn in the desired direction.
